Product Note: Failed or Burned Up VW/Audi Coils are Most Commonly Caused By Poor Electrical Connections, Wire Harness Breaks or Fouled Spark Plugs. New Connectors Should be Replaced When replacing Ignition Coils, Especially If There Has Been More Than One Coil Failure. A Loose Connection (Caused by Engine Vibration, a Cracked Connector Housing, Cracked or Broken Wire Insulation) Can Cause a Voltage Spike Which May Not Only Destroy or Burn Up the Ignition Coil, But Also the Neighboring Coil Because the Harness Wires are Bridged Together. The OE Connectors Are Not Designed to be Repeatedly Unplugged and Re-Plugged. VAG Recommends Replacing the Connectors if There is a Chance of a Loose Connection.
